When the building is located near high-voltage transmission lines, the people working or living in the building will absorb a certain amount of electromagnetic field energy. When the limit is exceeded, it will have an impact on human health. We studied people in surrounding buildings of 500kV EHV AC transmission lines and 1000kV AC UHV transmission lines and discussed electromagnetic field energy they absorbed.

Boundary Distance

Сформулирована и детализирована методика оценивания граничной дальности береговых ОВЧ радиостанций в направлении Берег-Судно, которая основана на зависимостях напряженности поля, полученных эмпирическим путем. Определены численные значения граничной дальности ОВЧ радиосвязи применительно к типовому судовому радиооборудованию и шумовой обстановке вблизи судовой антенны. Проведена оценка максимальных допусков определения граничной дальности ОВЧ радиосвязи. The procedure for estimating the boundary distance of the shore VHF radio stations in the shore-to-ship direction, which is based on the dependences of the electromagnetic field strength obtained empirically, has been formulated and detailed. Numerical values of the boundary distance of VHF radio communication in relation to typical ship radio equipment and the noise environment near the ship's antenna are determined. The estimation of the maximum tolerances for determining the boundary distance of VHF radio communication is carried out.

High Voltage Transmission

We present the multi-physical analysis of the induction-corrosion process undergone by a buried pipe subject to electromagnetic induction from a nearby High Voltage Transmission Line (HVTL). The scenario analyzed models a typical situation found in Colombia by using realistic characteristics of the pipe, the HVTL, and environmental parameters such as soil resistivity. The results presented provide a quantitative view of the corrosion process and constitute a useful tool for the analysis and design of the increasingly common situation of pipelines running near HVTLs.

Increasingly, induction heaters are being widely applied to the energy-saving light industrial equipment. But their electromagnetic radiation’s impact on the environment can’t be ignored. In the paper, several medium frequency induction heaters had been studied under different experimental conditions using E61 electromagnetic field strength analyzer, and as its supplement, the racetrack-coils induction heater had been simulated using ANSYS. According to ICNIRP guidelines, the results show that their radiation is generally in critical state, and magnetic field strength is superstandard in some areas. And countermeasures to the problems are advised.
